ASHVILLE, Ohio — Anduril will add production of the ALTIUS 600 to its Arsenal-1 manufacturing complex in Pickaway County, expanding the number of military weapon systems built at the site near Rickenbacker Airport to four. The ALTIUS 600 is an autonomous missile that can be launched from the ground, air or sea. Anduril said it is hiring workers for the new production line, citing increased demand for its systems. “Arsenal-1 was designed to give Anduril the capacity and flexibility to respond quickly to growing demand,” Kevin Kerr, the company’s vice president of production, said in a statement. “Expanding ALTIUS 600 production to Ohio is another example of that strategy becoming real.” Arsenal-1 already produces Fury, a pilotless aircraft; Barracuda, a missile; and Roadrunner, which the company describes as a hybrid of a drone and a reusable missile. The systems are manufactured in central Ohio and then transported to secure locations, generally outside the state, where explosives are added. The announcement comes as the war in Iran has continued for nearly seven months. Reports cited in the announcement say the conflict is contributing to U.S. ammunition shortages, and a Pentagon inspector general review last week concluded that American weapons inventories face shortfalls. Anduril executives have also said the company’s products are being used in the conflict. An underwater drone associated with the company was reportedly captured by Iran, according to previous reports. Matt Grimm, Anduril’s chief operating officer and a co-founder, said the company is responding to changes in modern warfare, including the increasing use of artificial-intelligence-enabled drones. He argued that the military needs weapons that are less expensive and can be manufactured and scaled more quickly. “It’s really just an evolution of warfare that has necessitated this kind of smaller, cheaper, more manufacturable, more scalable type of intercept system,” Grimm said. Workers hired for the ALTIUS line will initially train on existing production lines outside Ohio before returning to help train additional employees. The first group is expected to spend one month in California and two months in Atlanta. Anduril has said Arsenal-1 is expected to employ more than 4,000 people by 2035. The company has described the project as the largest single job investment site in Ohio history, while the expansion also gives the region a growing role in the production of weapons for U.S. military contracts.
